I've communicated with the manufacturers of the cdrom backpack. They insist that the necessary drivers are included in Microsoft Windows systems. That the backpack does not have proprietary drivers. That they have no drivers to offer. At first the lappy would not recognize the cdrom drive. Got the drivers from driverguide.com, problem resolved. Then the sound, video, and game controllers were xed out on device manager. Now, it has both identified the drivers needed and installed them, problem corrected. But no sound. I get sound from the labtop itslelf, but not from the cdrom. The tray (backpack) the new cdrom is attached to is the one the original cdrom (a much slower reader) was connected to. The labtop correctly identifies the IDE cdrom now, it plays VCDs, but no sound. I am able to install, very very slowly, games and play, but no sound. It really doesn't help that the labtop itself is ancient-Compaq WIN95, 1.36G Hard Drive, 120Mghz Intel Pentium, 32Mgbs of memory. I just want to get a system going on which my partner could play games and stop messing, and messing up my desktop.
